Abstract
The present application relates to methods and apparatuses for beam failure recovery (BFR) transmission. An embodiment of the present disclosure provides a method performed by a user equipment (UE), including: receiving first configuration information configuring a plurality of beam failure detection reference signal (BFD-RS) sets for a first set of cells, wherein each cell of the first set of cells is configured with two BFD-RS sets: receiving second configuration information configuring two physical uplink control channel scheduling request (PUCCH-SR) resources, wherein the two PUCCH-SR resources comprise a first PUCCH-SR resource and a second PUCCH-SR resource; and when at least one BFD-RS set of the plurality of BFD-RS sets is failed, selecting a PUCCH-SR resource from the two PUCCH-SR resources for transmitting a positive link recovery request (LRR) of the first set of cells based at least in part on whether two BFD-RS sets are configured for a first cell in which the two PUCCH-SR resources are configured to be transmitted.
